Patent GB-2086619-A (GB)
Title: Alarm timepiece
IPC: G04G13/02
Filed: 1981-10-20
Abstract: An alarm timepiece produces a musical melody at a pre-set alarm time and an animated visual display in synchronism, with the melody. The timepiece includes a time counter (4) and an alarm time memory (14). The output of the time counter (4) is displayed as time information on an optical display unit (7). When the time output from the time counter (4) coincides with an alarm time stored in the alarm time memory (14), a coincidence circuit (15) generates an output to control a melody generating circuit (M), whereby the animated display on the optical display unit (7) is effected according to a note code signal generated from the melody generating circuit (M) at this time.   <IMAGE>

Title: System for Determining Distance Velocity and Acceleration
IPC: G01P1/12
Filed: 1982-01-29
Abstract: A system for the measurement of the distance travelled, velocity and acceleration of linear, rotary or reciprocating motion, utilises a scale and an interacting sensor unit, one mounted on the moving part and the other on the fixed part and a microprocessor which calculates and displays the desired results from the interactions between scale and sensor. In the preferred embodiment, the device can measure or compare the quality of the ride of a lift or elevator car. A film strip comprising alternate exposed and unexposed portions is fixed up the length of the lift shaft and interacts with a photoelectric sensor on the lift. A velocity-time graph is produced by the microprocessor as a measure of ride quality and may be stored and compared with the ride at a later date. The sensor may alternatively be inductive, magnetic or fluidic. <IMAGE>
Patent GB-2117527-A (GB)
Title: Acoustic-optic device
Inventor: WRIGHT STEPHEN
IPC: G02F1/125
Filed: 1982-03-25
Abstract: An acoustic-optic device in which the light beam is converted in mode or polarization as it is diffracted and thus having a dynamic range making it applicable for use in a spectrum analyser. A TM optic beam (24) is guided in a waveguide comprised by a metal indiffused or ion implanted region of a substrate such as lithium niobate (piezo-electric and electro-optic). The TM optic beam (24) is anisotropically Bragg diffracted by a surface acoustic wave (SAW) launched from a transducer (23). The TE diffracted beam (28) is orthogonally polarised with respect to the incident beam and can thus be filtered from the scattered light of the TM incident beam (29), by means for example of an attenuating metallised layer (27). The polarisation conversion is achieved by means of an electro-optic interaction. Another metallised layer (26) over the acousto-optic interaction region may be provided to enhance the polarisation conversion. In addition to improving dynamic range, the modified (anisotropic) Bragg diffraction employed can result in a greater efficiency- bandwidth product. <IMAGE>

Title: Carpet rolling machine
Inventor: BARLOW JOHN MICHAEL
IPC: B65H19/30
Filed: 1982-10-22
Abstract: A carpet rolling machine has a pair of drivable rollers (14, 16), arranged to define a supporting nip on which a roll of carpet can be formed. A lower deflector (34) between the rollers (14, 16) presents an upwardly facing slide surface. An upper defector (20) is 3 moveable between a first position wherein it is disposed above the lower deflector and a rest position remote from the first position. In the first position the upper deflector presents a downwardly facing slide surface which together with the slide surface of the lower deflector and the adjacent rollers define a cylindrical space into which the end of a piece of carper can be fed and constrained to follow a cylindrical path to form an incipient roll with or without the use of a core (30). The lower deflector is pivotable between positions wherein it contacts one or the other of the rollers enabling a pile-in or pile-out roll to be formed (as in Figs. 6 and 7). A gate (70) is provided upstream of the lower deflector to direct the feed end to one or the other side of the feed roller (46) and lower deflector (34). <IMAGE>

Title: Improvements in Astrological Calendars
Inventor: LEE PO-MAN
IPC: G09B27/00
Filed: 1983-03-31
Abstract: A calendar provides information relating the positions of sun, moon and other planets to the Gregorian calendar. The calendar has a marker 4 on which is a flat projection of the celestial sphere. A heavenly bodies position chart is movable relative the marker and is marked with the relative positions 30a-36a of the heavenly bodies and the calendar date 41. The relative positions of the heavenly bodies on any particular day are given by an indicator means 24 which exposes the relative positions on a given date. An indicator 54 is provided having time scales corresponding to the local time of the observer to allow the corresponding local hour angle of a celestial body to be read from the indicator. Since the projection of the celestial sphere becomes more and more inaccurate as the observer becomes more remote from the equator, an adjustment for this is preferably provided. <IMAGE>

Title: Manufacturing mastic asphalt blocks
Inventor: POPE BRYAN
IPC: C10C3/18
Filed: 1983-10-28
Abstract: In an installation for manufacturing mastic asphalt hot bitumen mixed with hot limestone filler and unheated grit is a mixer from which the asphalt is discharged into a plurality of moulds 52 in order to mould blocks. The filled moulds 52 are conveyed by a conveyer 54 through a cooling tower 50 in which they pass through an array 56 of spray nozzles arranged to spray water onto the moulds 52 so that at least some of the water impinging on the moulds 52 initially forms steam and thereby cools the asphalt. Inside the cooling tower 50 the moulds 52 are conveyed along a vertical zig-zag path so as to fit a relatively long cooling path into a relatively small ground area. The mastic asphalt blocks produced have at least one groove formed in their upper surface. Heat is extracted from the asphalt in the mixer and returned to the means for heating the limestone filler. A microprocessor controls the filling of the moulds 52 in order to render the weight of the moulded blocks substantially consistent. <IMAGE>

Abstract: An automatic speed control system particularly for use with coaches has a comparator 12 for comparing the actual road speed of the vehicle with a reference to produce an error signal for controlling the engine power via a control unit 18 so as to hold the vehicle at the desired speed. In addition the error signal is fed to a comparator 52 which, if the error signal indicates too high an excess speed, provides positive retardation of the vehicle via a retardation unit 30 which may be the actual brakes of the vehicle or (preferably) its electric retarder. A comparator 54 may also be arranged to be responsive to excess engine speed and to actuate the retarder via an OR gate 60. <IMAGE>

Title: Mechanical stepless kinematic and torque converter
Inventor: SPACHI ROBERT
IPC: F16H59/16
Filed: 1984-04-06
Abstract: A continuously variable torque converter consists for a shaft 7 journalled in two eccentric housing parts 1, 3 interconnected by a control disc 2 provided with a groove of a logarithmic spiral shape. A pin 4 engages in the groove via a roller 19 and is secured to the shaft 7 so as to extend transversely from the latter.
